Abstract
Provided is a crosslinked rubber having excellent workability and heat resistance, and a crosslinkable rubber composition that can be used to form the crosslinked rubber. The crosslinkable rubber composition contains: a rubber including a carboxyl group-containing ethylenically unsaturated monomer unit; an amine-based crosslinking agent having a melting point of at least 50° C. and no higher than 180° C.; and one or more carbon nanotubes. The crosslinked rubber is obtainable through crosslinking of the crosslinkable rubber composition. The carbon nanotubes preferably have a BET specific surface area of from 600 m/g to 2,000 m/g.
